Product FAQs
7 answersWhat does the "-1021" suffix indicate on the FAL34070-1021?
The "-1021" suffix denotes a factory-installed 120/240VAC shunt trip. This allows the circuit breaker to be opened remotely via an external voltage signal, which is commonly required for emergency shutdown systems.
What is the modern replacement for the legacy FAL34070-1021?
The Square D FAL series is a legacy F-Frame breaker. For new installations or modern retrofits, it is typically replaced by the PowerPact B-Frame series, such as the BDL36070, equipped with a compatible shunt trip accessory.
Can the FAL34070-1021 be installed in a Square D I-Line panelboard?
No, the FAL34070-1021 is a unit-mount circuit breaker designed for enclosures, switchboards, and motor control centers. It lacks the plug-on jaw connections required for I-Line panelboards.
Does the FAL34070-1021 require external lugs for wiring?
No, this breaker includes factory-installed line and load lugs. The lugs accept 14 to 1/0 AWG copper or 12 to 1/0 AWG aluminum conductors.
Are the thermal and magnetic trip points adjustable on this breaker?
No, the FAL34070-1021 features fixed thermal (long-time) and fixed magnetic (instantaneous) trip settings. Applications requiring adjustable trip curves must use a breaker with an electronic trip unit.
How is the factory-installed shunt trip utilized in safety systems?
The integrated 120/240VAC shunt trip allows the breaker to be wired into emergency stop circuits, fire alarm panels, or remote safety interlocks, ensuring automatic power disconnection during a fault or emergency event.
Is the FAL34070-1021 rated for use in DC power systems?
Yes, this thermal-magnetic breaker is rated for DC applications up to 250VDC, providing a 10kA interrupting capacity for DC circuits.
